A North America “Free Toes” Alliance (NAFTA)? Teaming up to #ActAgainstAmputation worldwide #DiabeticFoot @VascularSVS @APMA

This work from our friends from Mexico City, Toronto and our team, stems from a lecture series that Joe Mills and I created several years ago entitled “The North American Free Toes Alliance” featuring Mexican Vascular Surgeon Dra. Rocio Jimenez. This was revisited by Dr. Carlos Hinojosa in “Renegotiating NAFTA”. It was Carlos’ leadership that created this manuscript. Enjoy!

The importance of establishing a framework
for regional and international collaboration in
the management of the diabetic foot

The global prevalence of diabetes mellitus continues to rise; estimates are that it will affect 350 million people (4.4% of the global population) by the year 2030.1 Associated complications of diabetes are likewise increasing.2 Diabetic foot ulceration (DFU) is complex and costly, being the most frequent cause of hospitalization in this population of patients.2,3 In Mexico, there are approximately 12 million people with diabetes mellitus, and the health care cost is 2.3% of the gross domestic product, mostly to treat complications associated with DFU.3 Last year, the Department of Surgery of the National Institute of Medical Sciences and Nutrition Salvador Zubirán in Mexico City held a multi- disciplinary congress with 44 participating panelists who analyzed 126 proposals for DFU management. The conclusions and recommendations derived from this meeting emphasized the need for updated classification systems 4 and clinical practice guidelines,2 the publication of a position document in Mexico, and the development of courses by qualified and certified groups supported by the National Academy of Medicine for the preparation and training of health care providers in this area.5,6
Communication in health care has always been and still remains a key element in the exchange of scientific knowledge; clinical experience; and modification or reinforcement of behaviors, values, and social norms that ultimately contribute to positive self-care practices,

quality of life, and better patient-physician relationships. In October 2018, the Diabetic Foot International Conference (DFCon) was held in Houston, Texas, during which a world-renowned faculty composed of multiple clinical disciplines, innovators, and researchers from Europe, Asia, Oceania, Africa, and the Americas discussed important topics in this area.7 This led a notable forum to propose a North American Free Toes Alliance (NAFTA), an acronym used for 24 years in the Trade Agreement between the United States, Canada, and Mexico. The North American Free Trade Agreement (NAFTA) has bound the economies together since 1994, removing import and export barriers. The proposed “North American Free Toes Alliance” would strive to develop and to integrate a regional, trinational regis- try to evaluate clinical outcomes in the management of DFU. This international initiative could simultaneously serve as an important platform for patients seeking centers of excellence for DFU care. We are convinced that the evaluation of our initial results by a third, independent organization such as the International Working Group on the Diabetic Foot would be crucial and an important pathway toward the possible adaptation and implementation of such multinational efforts in other regions of the world.8
The optimization of communication and the design of effective platforms will allow the generation of new and available and, more important, public medical information, research protocols, and practice guidelines. The creation of an international standard of medical care and opportunities for academic exchange of information would be the primary objectives of this effort. This effort could serve as a model for other regions across the globe.
